Our First IR Board pic chip died during the Hartford regional. I’m trying to order a new pic before the NYC regional but the big Integrated Circuit suppliers don’t have them in stock, Digikey, Newark, Jameco… any suggestions of sites or places to get one relatively soon?
Microchip Direct (www.microchipdirect.com) is the only place our team has been able to find them. They do typically ship from Thailand, so timing may be an issue if you want them for NYC. Also, I don’t believe the surface mount packages (that’s what the “-I/SO” means) are in stock.
We are using a DIP package as our backup. It’s pin for pin identical, but lead spacing and other things are different, so some wiring has to be done.

Look for -E/SO. That is just extended temp range.
Or without the L (L is just the low voltage version good down to ~3.3V - shouldn’t matter @ 5V). PIC16F87-I/SO should be much more available.
The same hex file should work on either.
You’re looking at a simple search algorithm that microchip uses. Since you are entering a string “PIC16LF87”, you’re going to get anything that begins with that string (like PIC16LF870, PIC16LF871…etc). I suppose that’s a flaw in the microchip search engine, but that’s how it works.
Search for “PIC16LF87-I” and that will give you all the (standard temperature range) packages for the PICLF87. (http://www.microchipdirect.com/productsearch.aspx?Keywords=PIC16LF87-I)
You may also find another PIC16LF87 with different suffix (instead of -I). These would be either RoHS compliant or the extended temperature range version of the device. They should be pin for pin identical, but I’m not sure if they will accept the program for a PIC16LF87-I device.

EDIT: Kudos to BrianBSL on the pickup. I’m not sure if Microchip makes the LF for extended temp, but the PIC16F87-E/SO exists. Again, I am unsure if the extended temp version or non-LF version can accept a program compiled for the original PIC16LF87.
